In DSC curve the melting point is the maximum height where crystals melt completely and heat flow shows it least value and further increase in heat flow happens since thermal transition is over.

Thanks a lot.

Why hear flow increase after melting

do you have the file? thank you~~~

It's normal dsc curves.

Thanks

Good question, see the macrogalleria site for a basic explanation of first and 2nd order transitions on DSC and the pdf on the TA website for some more details on the shape of the curve in a first order transition:
